No account. No subscription. No ads. No analytics. No cloud database.
Whether you're studying, researching, reading documentation, comparing products, applying for jobs, planning a trip, or simply saving interesting things you find online, Markd turns your browser into a personal research workspace.
๐ WEB HIGHLIGHTER
Select text on almost any webpage and save it as a highlight.
Create highlights using the on-page button, the Alt+H keyboard shortcut, or Chrome's right-click menu.
Choose from preset highlight colors or create your own custom colors. Add notes, tags, and projects to your highlights, then return to the page later and Markd restores them automatically.
Your highlights remain connected to the original webpage, making it easy to revisit the source and understand the context in which you saved something.
Markd works as a web highlighter, article highlighter, study highlighter, research annotation tool, and documentation highlighter without requiring you to copy everything into another app.
๐ ADD NOTES TO HIGHLIGHTS
Turn highlighted text into useful research notes.
Click a highlight to add your own explanation, summary, question, reminder, or idea.
Notes support bold, italic, underline, headings, bullet lists, numbered lists, strikethrough, and inline code.
Hover over a highlighted passage to quickly preview its note while staying on the webpage.
This makes it easy to annotate articles, research papers, documentation, tutorials, course material, and other online reading.
๐ STICKY NOTES ON WEBPAGES
Add sticky notes directly to websites without opening another app.
Create a sticky note with Alt+S or Chrome's right-click menu.
Sticky notes can be moved, resized, recolored, formatted, positioned beside selected text, attached to a place on the webpage, or pinned to your browser window while you scroll.
Use browser sticky notes for reminders, questions, ideas, explanations, summaries, to-do items, or anything you want to remember while browsing.
๐ SAVE WEBPAGES AND BOOKMARKS
Found something useful but don't need to highlight it yet?
Save the entire webpage to your Markd research library.
Give saved pages your own title, description, tags, and projects.
Markd also automatically remembers a webpage whenever you create a highlight or sticky note on it.
Instead of keeping dozens of tabs open, save useful articles, documentation, resources, products, job listings, research sources, or reading material and find them again later.
๐ ORGANIZE RESEARCH WITH PROJECTS
Create projects to keep related research together.
Projects can be used for courses, essays, research papers, programming topics, job searches, personal projects, product research, travel planning, reading lists, assignments, and anything else you're researching.
Choose an active project and Markd can automatically organize new highlights and notes into it.
The same page or annotation can belong to multiple projects, so you aren't forced into a single folder structure.
๐ท๏ธ ORGANIZE WITH TAGS
Add tags to highlights, sticky notes, and saved webpages.
For example:
important
exam
evidence
read-later
idea
python
research
Use tags alongside projects to build a research system that works for you.
You can later filter your library by tag, project, website, annotation type, or highlight color.
๐ SEARCH ALL YOUR NOTES AND RESEARCH
Markd gives you one search box for everything you've saved.
Search highlighted text, highlight notes, sticky notes, page titles, page descriptions, URLs, websites, tags, projects, and highlight colors.
Markd also supports search filters such as:
tag:evidence
project:"Literature Review"
site:wikipedia.org
color:yellow
type:highlight
Combine filters to quickly narrow down a large research library and find exactly what you saved.
๐ BROWSER SIDEBAR
Open the Markd sidebar while staying on the webpage you're currently reading.
From the sidebar you can see everything saved from the current page, search your research library, edit notes, add and remove tags, organize highlights into projects, jump directly to highlights, and reveal saved annotations on their original webpage.
Markd works alongside your normal browsing instead of forcing you into a separate note-taking workflow.
๐๏ธ FULL RESEARCH WORKSPACE
Open the Markd workspace when you want a complete view of everything you've collected.
Browse your research by pages, highlights, sticky notes, projects, tags, websites, colors, search, and archive.
Switch between grid, list, and masonry views to manage larger collections.
Markd combines web highlighting, bookmarking, note-taking, and research organization into one browser workspace.
โ ORGANIZE MULTIPLE ITEMS AT ONCE
Managing a large research library doesn't have to mean editing everything one item at a time.
Select multiple pages or annotations to add tags, assign projects, export items, or delete items.
You can also reorder annotations so the information most important to you stays near the top.
